The distance from one Linn to the other may be half a mile or more, along the same ell-wide walk. We came to a pleasure-house, of which the little girl had the key; she said it was called the Fog-house, because it was lined with "fog," namely moss. On the outside it resembled some of the huts in the prints belonging to Captain Cook's Voyages, and within was like a hay-stack scooped out. It was circular, with a dome-like roof, a seat all round fixed to the wall, and a table in the middle,--seat, wall, roof, and table all covered with moss in the neatest manner possible. It was as snug as a bird's nest; I wish we had such a one at the top of our orchard, only a great deal smaller. We afterwards found that huts of the same kind were common in the pleasure-grounds of Scotland; but we never saw any that were so beautifully wrought as this. It had, however, little else to recommend it, the situation being chosen without judgment; there was no prospect from it, nor was it a place of seclusion and retirement, for it stood close to the ell-wide gravel walk. We wished we could have shoved it about a hundred yards further on, when we arrived at a bench which was also close to the walk, for just below the bench, the walk elbowing out into a circle, there was a beautiful spring of clear water, which we could see rise up continually, at the bottom of a round stone basin full to the brim, the water gushing out at a little outlet and passing away under the walk. A reason was wanted for placing the hut where it is; what a good one would this little spring have furnished for bringing it hither! Along the whole of the path were openings at intervals for views of the river, but, as almost always happens in gentlemen's grounds, they were injudiciously managed; you were prepared for a dead stand--by a parapet, a painted seat, or some other device.
